SP'NDLE BEARING.

Application filed September To all whom it may Gomera: i

Be it known that I, JoHANN .Lioo KnYsni-l, a citizen of Switzerland, anda resident of Rain 111, in the city of Aarau, in Switzerland, haveinvented certain new and useful Spindle Bearings, of which the followingis a specification.

This invention has reference to novel means of resiliently journaling'the top portion of spindles for spinning and t-Wisting machines and thelike, and it is particularly intended to provide more generallyapplioable collar bearing -of the kind referred to as compared with theprevious art, and to generally improve and perfect the construction andto facilitate the operation of devices of this kind. In accordance Withthe previous art the upper journal bearing of spindles of the kindreferred tol has been supported by struttingly acting radially mountedSprings resting against the casing; but this kind of arrangement hasonly been employed in connection With spindles operated by belts or thelike, and in this case it has merely served for the absorption of thepull of the belt. In the case of positively acting means, hoWever, beingem- `ployed for the driving of the spindles, such `as operation by bevelgear Wheels, skeW Wheels, helical Wheels or the like the springactuating arrangements heretofore in use either operate veryunsatsfactorily or refuse to Work at all in vieW of the fact that in thedriving of the spindles an increased tendency is imparted to the bearingto participate in the rotation of the spindle shaft, resulting in thejamming of the springs in their guides and the consequentinoperativeness of the device. This very serious drawback is especiallynoticeable in the operation of large spindles by positive means, such asare required for instance in the case of the twisting of artificialsilk.

My invention is intended to overcome these difliculties, and in viewthereof the elastic or resilient elements, such as Springs or the likefor the lateral support of the journal bearing are only retained attheir ends, the outer bearing being formed by a steel band embracing theouter extremitiesv of the resilient elements, and permitting easy andperfect insertion of the bearing and of the springs into the socketprovided therefor, and Without tWisting or injuring the Springs retainedby the steel ribbon, and

thcreby prcventing inoperativeness of the same.

The invention Will be more fully described With reference to theaccompanying draWing showing by Way of example an embodiment of theinvention in Figure 1 as a Vertical longitudinal section through aspindle operated by positive means. Figure 2 shoWs on an enlarged scalethe mounting of the resilient means in plan view. Flgure 3 is a sectionthrough the upper bearing for` particularly heavy spindles.

rlhe spindle 1 is positively rotated by a Wheel 2 or by equivalent meansengaging with a Worm gear on the spindle. The bottom ball bearing of thespindle at 3 is stationarily mounted. The upper ball bearing 4 for thespindle is mounted in an oil cup 5 Which is seated in a guide betweenthe casing 6 and the cover 7. Around the oil cup 5 and between the rim 8of the cover 7 and the oil cup 5 a plurality of radially arrangedelastic or resilient bodies 9 of rubber or helical Springs 10 arearranged Which act as supporting struts of the bearing 4 and of the oilcup 5 relatively to the cover 7. In order to maintain the elastic bodies9 or the Springs 10 in the proper position With relation to the cover, asteel band 11 is provided which is provided With stamped out projections12 situated between the several Springs 10 or the bodies 9. This steelband is divided at 13 so that the endS Will overlap each other. By meansthereof the advantage is produced that all Springs 1G or bodies 9 may becompressed thereby, so as to introduce them simultaneously into theprojecting rim 8 of the cover, and Without any liability of tWisting orstra-ining of the Springs or bodies referred to. The projections 12 aremoreover shaped in such al manner as not to interfere at all With themovement of the Springs, but providing for the utilization of thecomplete and uniform spring action of the elements.

n accordance With the iuodilication of lfigiu'e 3 the oil cap has anextension, proferably in form of a rii'n 1= of smaller diameter than theball bearing, so that in this construction Without changing the outerdianieter of the bearing" casing 6, and With the same sizes of theelustic bodes or Springs 10 a. ball bearing of considcrably greaterdiameter may bo used, such as is required for heavy spindles. This is apoint of importance Whenevei' it necessary to i'educe the diameter ofthe heads o'if the several spindles, when they are ari'anajed at smalldistanees from each other, so as to be able to mount the spindles inexisting oi' other spinning 01' twistine; machines with cl'oselyarranged spindles.

rlhe invention has been shown and de'- sei'ibed in its bi'oad aspects,and it is obvious that it is capable ot modifieations and changes withinthe nieaning`|` of the ":lainis hel'eunto appended and Without deviatingfrom the spirit ot the invenioa.
